thank you, I think I'm going to do it! I'm sure they are old enough to 'get it', I mean I don't think I'd do it for my younger neices and nephews but at their age I'm pretty sure it'll be ok. The first time I was in Africa the oldest half sister was 13 at the time, and she sent over some things she had made for me to give to the kids there and also was very interested in having a penpal there.. the more I think about it, the more confident I am they will be happy
